The original Foa Causeway linking Lifuka Island to Foa Island was built by New Zealand Army engineers beginning April 1979 and completed in February 1980. This causeway was severely damaged by tropical cyclones over the years. As part of infrastructure development initiated by the Government of Tonga, the Republic of the Federal Republic of Germany agreed to fund the upgrading of the Foa Causeway.
The Upgraded Causeway is comprised of two reinforced concrete walls and a tarsealed road between the two walls and three double box culverts (for free flow of water under the Causeway) and two side- bays to allow for give-ways and the passing of vehicles.
- Length of Retaining Walls 1,150m (both sides)
- Three Twin Culverts 2No. x 4.5m clear length x 2m clear height
- Total Length of Upgrade work 680m
